Just do what Duster said
I have had Corbin saddles on three different BMW airheads, the first one was great after it broke in ( several thousand miles) the other two just plain sucked, had to be sent back for re works . Their warranty says they will pay for one redo, but you pay for shipping EACH WAY, and funny how the seats each required a new cover since the first one no longer fit,
yep you got it AT YOUR EXPENSE.
The company has changed significantly over the years, it's been up for sale for a long time, the complaints are legion about customer service and missed delivery times over on the BMWMOA forum.
Fa get about it ! just call Cary , and your butt will thank you
